' DYEiNG-MAGHINE.

To all/whom t may concern:

Be it known that I, I-IowARD M. DUDLEY, a citizen of the 'United States,and a resident of Philadelphia, in the ycounty of Philadelphia andrState of Pennsylvania, have in? vented certain new and usefulImprovements in Dyeing-Machines, o f which the fol-r lowing isaspecification. v

My invention refers tol dyeing machines and refers particularly to amachine suitable for the dyeing ofworsted top and warp balls. n y .y l

One object of my invention is a device whereby worsted top, warp ballsand similar fibers may -be thoroughly and evenly dyed and treated withliquids and air.;y

Another object of my invention is a device whereby ibers in thecondition stated above may be dyed and treated without injury to theliber. i I y f Another object of my invention is a device whereby fibersin they condition stated above may be readily and rapidly packed intodyeing chambers and compressed into a form suitable for evenpenetration.

Another object of my invention is a device whereby a considerable numberof balls, tops, &c., may be dyed equally.

rlfhese and other objects of vmy invention will be evident upon aconsideration of myv specification and claims.

The dyeing of worsted tops, warp balls and similar ibers presentsseveral difficulties which must be overcome in order to produce oven andsatisfactory results. A

0n account ofthe physical condition of the bers, they mustv not bev.disturbed during the d veing yoperation .but must be re? tained intheir original untangled condition.

,On account ofthe shape of the tops or balls, it is diflicult to obtainsatisfactory results by placing themin layers, each layer comprised of aAnumber of tops or balls, as when compressed, channels or openings areliable to be formedbetween thetops and balls, as it is difficult tocompressthem all into a uniform mass for the passage of the liquid.

which the dye liquor enters the fiber mass, and that unevenness can beprevented by the use'of-openings of a particular shape,v

or oxidizing products, for the purpose of after-treatment, or withoxygen or air for oxidizing or dryingpurposes. In the following ofitheseafter-treatments it isessential ythat every portion of the dyed goods fbe thoroughly and uniformly treated and that the operation be performedas readily and quicklyas possible. All of these results are obtainableby the use of the device of my invention, in which the goods are placedinf-the dyeing chamber and then rapidly,

easily and completely dyed and after-treated without further handling ofthe1 goods and without the formation of channels by the liquidsemployed. The device therefore insures even and uniform results with aminif mum of time, labor and expense.

1n the form of my devicev as illustrated in .the accompanying drawings,the truck 20 is mounted upon the wheels 21, 21, which are capable ofmovement upon. the tracks 22, Pivotally mounted upon the truck 20, is areceptacle 23, iiXedly attached to the pinion 24 which is revolublewithin the trame Fixedly attached to the pinion 24 is a toothedsegmental wheel 26, meshing with the teeth of the worm`27. The worm 27is revoluble within the supports 28, 28, mounted upon the truck 20 andis capable of revolution by revolving the wheel 29 lixedly attached tothe shaft 30 of the worm 27. The turning` of the wheel 29 thereforerevolves the receptacle 23 through the medium of the worm 27 and thetoothed wheel 26. The outer cylindrical wall of receptacle 23 iscomprised of the shell 31 which extends upwardly and outwardly into themembers 32, 32A, forming the cylindrical chambers 33, 33A.

At the two ends of the ieceptacle 23 are the hollow members 64, 64Aextended into the hollow members 65, 65A. The larger end oil each of themembers 64, 64A is of the same size and shape as the members 32 32A,upon which it is capable of abutment, and carries the angular collars66, 66A, capable of engagement with the annular member 70, 70A of themembers 32, 32A.

The method of attaching the members 64, 64A to the shells 32, 32A is asfollows, as shown in Figs. 2 and 4: A compressible gasket 82, 82 isinserted between the pyramidal shaped flange members 66 and 70, thegasket being preferably foi-'med of a number of pieces. The clampingmember 59 is closedupon its hinge 60, the inclined inner faces of theclamping member abutting upon the inclined outer faces of the iangemembers 66 and 70, and the joint between the two Hange members madetight by the pressure carried by means of the thumb- Screw 61.

Connected with the cylindrical chambers 33, 33A are the pipes 34, 34Acarrying the valves 35, 35A and converging into the pipe 36 which entersthe upper portion of the tank 37.

The receptacle 23 also carries the pipe 117 with the valve 118.

The centrifugal pumps 71, 71A are connected at their discharge ends withthe members 65, 65A by means of the pipes 120, 120A carrying the valves121, 121", The charging ends of the pumps 71, 71A are connected withthree-way pipes 73, 73A, which three-way pipes are connected with thepipes 74, 74A carrying the valves 7 5, 7 5A, the pipes 76, 76A carryingthe valves 77, 77A and the pipes 78,

78A carrying the valves 79, 79A. The pipes 74, 74A lead to a source ofwater supply, the pipes 7 6, 76A lead to the bottom of the liquidreserve tank 37, which is situated above the pumps 71, 71A and the pipes78, 7 8A lead to a tank containing the liquid in which the dye isdissolved. Connected with the pumps 71, 7'1A respectively are thetwo-way pipes 85, 85A, branching into the pipes 86, 86A carrying thevalves 87, 87A and opening into the air, and the pipes 88, 88A carryingthe valves 89, 89A, connected with an exhaust and compression pump notshown.

Within the conical members 64, 64A are the imperforate conical members80, 80A, capable yof abutment upon the imperforate cylindrical member116 which is situated within the receptacle 23. The members 80, 80A aresupported by the bar supports 81, 81A.

Within the receptacle 23 are a series of hollow cylindrical chambers 90,90, having imperforate side walls l91, the ends being open. Within oneend of each of the hollow cylindrical chambers 90, 90 is a foraminousplate 92, rest-ing upon the annular abutment 93. Vithin the other end ofthe chamber 90 is a slidably movable oraminous plate 94, which is movedby the revolution of the threaded member 95 which is meshed with thethreads 96 within the chamber 90, the member 95 being capable of.abutment upon the plate 94.

Within the exterior wall of each cylindrical member 90 are the conduits100, 100A, carrying the valves 101, 101A. The c0nstruction of thesevalves is shown in Figs. 5, 6 and 7. The stem 102 has the one-way port103, the pin 104 is inserted in the groove 105 to prevent the withdrawalof the valve stem 10.2, and the stop-pin 106 sets the valve for the freepassage of liquid through the conduit 100A or for the complete stoppageof such passage.

Vithin the wall of each cylinder (see Figs. 5, 6 and 7) is a chamber107, into which the conduits 100, 100A lead, said chamber being'threaded upon its inner surface. A threaded cap 108, capable ofenmeshment with the threads of the chamber 107, is slidably movable overthe testing tube 109. 1n order to insert the testing tube 109, the twocaps 108, 10.8 are slid inwardly upon the testing tube, the tubeinserted between the two openings of the conduit 100, 100A, and the twocaps 108, 108 threaded with the threads .of the chamber 107 and screwedinwardly until a tight joint is effected by means of the gasket 110.

Each of the foraniinous plates 92 and l94 is comprised of a series ofconcentric rings carrying upwardly 111, 111 and downwardly 112 112extended pointed members, between which are openings 113, 113 for thepassage of liquor.

Perforated steam pipes 115, 115A are within thechambers 33, 33A.

Theoperation of the vdevice is as follows, assuming thatthe dyeing ortreating operations have been finished and the device in the positionshown in the drawings z` All of the valves with the exceptionv of 118are closed, thus drawing off the liquid within the receptacle. The pipe36 is thenuncou pled. The series of screw-bolts 61, 61 are withdrawn,the clamping members 59, 59 opened and the gaskets 82, 82 removed, thusfreeingthe receptacle 23 from engaginent with the members 66, 66A.vTruck 20 is then withdrawnfrom its position by rolling it upon thetracks 22, 22, thus removing the receptacle from between the conicalmembers G4, 64A. The receptacle 23 is then given a quarterl revolutionbyk turning the wheel 29, andinay be maintained in this position, ifnecessary, ley-means of the screw bolt 130. The members 95, 95 arescrewed out o-f position, and the fiber 131, 131 is removed.

When it .is desired to load the device, ay

set of tops or balls 131, 131 is inserted within each cylindricalchamber 90, a foraminous plate 94 inserted within the chamber' andpressed downwardly upon they fiber by screw#V ing in the Ymember 95. fWhen each chamber 90 is thus loaded and packed, the device'isrevolvedinto an upright position, rolled in between the members 64, 64A,and tightly joined thereto by means ofthe gasket 82 and the clampingmembers 59, 59.

The apparatus is so arranged that the treating liquid may be passed ineither direction through the liber. To dye, all the valves are closedwith the exception of 77A, 91A, 35, 101 and 101A, and the 'pump 71Astarted. This draws the liquid from thek tank 37 through the pipe 7 6Aand forces it through the pipe 65A, the conical chamber 641A, and thencethrough the chamber 33A, the foraminous plate 92, the chambers 90, 90and the fiber 131 therein. Fromthence the liquor passes through theVforamino'us l plate 91', the chamber 33 andthe pipes 34 and 36 back intothe'tank 37. At the same time, the liquor is forced through the conduit100A, the testing tube 109, the conduit n 100 into the chamber 33 andfrom thence back into the. tank 37.

Then it is desired to reverse the flow of by opening the valve 118 atthe bottom thereof.

If it is desired to wash the goods, water is admitted through the pipes74, 74A by opening the valves 75 and 7 5A, and the water forced throughthe device and the goods contained therein, the other valves being insuch an open or closed position as to cause the water to enter eitherthrough the pipe 7d@` orpaA and exitA through the other one, thecirculation being caused by either the pump 71 or 71A. i

If it is desired to treat the dyed liber with air, the `valves' 87 and89A andthe exhaust pump (not shown) started, the'other valves beingarranged to allow air to be sucked in through the pipe 86, the deviceand fiber, by the suction upon the pipe SSA, or by using the compressionside ofthe pump '(not shown) air may be forced through the de- Vice andthe fiber in anopposite direction from that just described.

During all of these operations the valves 101 and 101A are maintained inan open condition, thus allowing the liber' in the smaller device 109 toreceive exactlythe same treatment as that in thelarger device, and thecondition of the fiber in the larger devicem'ay be determined at anytime without interrupting the process by closing the valves 101,l 101Aand examining the fiber `in the smaller device 109, by unscrewing themembers 108, 103 and removing the test tube 109 for examination.

One of the chief improvements in my device is the method whereby thedyeing chamber yand its contents may be removed from the source ofliquid supply without the necessity of handling, or moving the latter,thus effecting a very considerable saving in time of operationland Costof erection, and in presenting amethod whereby a 1number of dyeingchambers may be employed in an exactly similar' manner. y y
